To all whom it may concern.-

Be it known that I, DAVID W. JONES, acjtizen of the United States,residing in the city and county of San Francisco, State of California,have invented certain new and useful Improvements in Pumping Apparatus;and

'I do hereby declare the followingto be a full,

clear, and exact description of said inventlon, such as will enableothers skilled in the art to which it most nearly appertains to make,use, and practice the same.

My invention relates to a pumping appathousand feet or more, and theyare usually of small diameter and lined with a casing. My pump isadapted to be lowered inside this narrow casing and to be operated fromthe surface of the earth, all as hereinafter set forth and described.

Referring to the accompanying drawings, Figure 1 is aside elevationv ofmy pumping apparatus, having a portion at the lower end of the main pipehrokenaway to show the injection-nozzle and a portion at mid-lengthbrokenaway to show the check-valve. Fig. 2 is a side yiew of theinjection-nozzle. Fig. 3 is a. longitudinal section of theinjectionnozzle, and Fig. 4 is a side view of the sediment-valve and themeans for operating it.

Let A represent a pipe or tube which forms the main lift or dischargepipe of the apparatus. To one side'of the pipe A, near its lower end, aperforated suction-pipe B'is connected with the main pipe by means of anelbow O. This suction-pipe may, extend to a distance below the lower endof the main pipe A within the limit-of suction, as hereinafterdescribed.

D is a casting having two branches E and F. This casting is mountedbelow the main pipe A, and the upper end of one of its branches E isconnected with the lower end of the main pipe A by means of anozzle-fitting G, (shown in Figs. 2 and 3,) while its other branch F isconnected with the lower end of a pressure-pipe H, which extends upalongside and-parallel with the main pipe A. This latter pipe I-Iextends above the surface of the ground and is connected with aforcepump I of any desired pattern. The interior of the casting D formsa chamber for the purpose hereinafter described, and its lower end isprovided with a valve J, which can be opened or closed by means of twolevers 7.: Z and two wires m m, which lead up alongside on pipe H to thesurface.

The upper end of the main pipe A is connected by a pipe 0 with a tank P,while the tank is connected with the pump I by a pipe Q. 'lhis pipe 0isshown in the drawings by the dotted lines where it passes behind thepump. A cock 0" in the length of this pipe serves to open and close itspassage for the purpose hereinafter described. S is a checkvalve in themain or upraise pipe A.

The injection-uozzleG is constructed so as to constitute an ordinarypipe-fitting. It consists of a short tubular section marked 2, having apolygonal not 3 formed on one end and a short tapering'nozzle t on itsopposite end. ed, so as to screw into the end of a pipe, and the nut 3is provided with interior screwthreads, so that a pipe can, be screwedinto it, as shown at the broken-away portion at the lower of the mainpipe in Fig- 1. By constructing this injection-nozzle as an ordinarypipe-fitting it can be made in quantityot' different sizes and sold instock.

The suction and pipe attachments of this pumping apparatus can be madein compact form and of a dimensiop that will admit of them being loweredinto a driven or bored well of narrow compass until they reach thebottom or level of the liquid in the well and proper pipe extensionsconnected with the pipes A and H to reach the surface and be connectedwith the pump I and tank P, re-

spectively.

The pump I here shown is a hand-operated pump having a lever 4 fulcrumedat its lower The exterior of the section'2 is thread after which thevalve should be closed.

into the lower end of the main pipe A and. forces the liquid containedin it upward to the surface. It is apparent that the pressure in thedown-pipe H will balance thepressure in the main pipe A, so that anyadditional pressure induced by the action of pump I will cause anoverflow from the upper end of the main pipe, and as the liquid isthereby set in motion a vacuum will be .produced opposite the pointwhere the suction-pipe connects with it, and a consequent upwardmovement of the liquid is induced through the suction-pipe, which isalso raised and discharged through the main pipe. The tank P is suppliedbya flow through the pipe 0 from the upper end of the main or dischargepipe, and this supply is regulated by the cock 1'. Any sediment that maysettle in the chamber of casting D can be discharged when desired byopening the valve J by means of the wires m 'm and turning on thepump-pressure,if required, In the operation of this pump I can use steamor vapor instead of Water in the pressurepipe II.

This apparatus can be mainly constructed of ordinary pipes and fittings,such as can be found ready made onthe market, and it will form anefiectual pumping apparatus that can he adapted to one or more wells andoperated by a single pump.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is- I 1. A pumpingapparatus coinprisinga main ordischarge pipe: a suction-pipe connected with the lower end of the mainpipe: an in-, Jection-nozzle applied at the base of the main connectedat its upper end with a pump at the surface: a feed-pipe connecting theupper end of the main or discharge pipe with a tank and a pipeconnecting the tank with the side of the pump opposite its force-pipesubstantially as described.

2. In a pumping apparatus operated by a jet of water or vapor ejectedfrom anozzle into the main or discharge pipe, a tank connected with andsupplied with liquidor vapor from the upper end of the discharge-pi peand a feedpipe connecting said tank with the operatingpump by which theliquid or vapor is forcedthrough the injection-nozzle substantially asdescribed.

3. In a pumping apparatus operated by a jet of water or vapor ejectedfrom a nozzle into the lower end of a main or discharge pipe: a castingat the lowerend of the main pipehaving, two branches and whose interiorforms a sediment-chamber: an injection-nozzle connec ed with one branchof the' casting while its opposite branch is connected with thepressure-pipe, a valve in the lower endjof the casting below thesediment-chamber and a two-.

armed lever connected with the valve and operated by wires leading tothe surface for opening and closingthe valve substantially .asdescribed.

In witness whereof I have hereunto signed my name this 7th day of April,A. D. 1-902.

DAVID W. JONES.
